Abstract: FELDSPAR POLISHING COMPOSITION          Abstract of the Disclosure:           A specific particle size distribution of feldspar is employed as both a cleaning and a polish-ing agent for teeth.  It consists initially of a powder that, preferably at the time of use, is mixed with a moistener and becomes a paste to be used by the dentist or dental hygienist.  It can be combined with a humectant but in smaller proportions than heretofore.          It can be used with or without a dental caries-reducing amount of a fluoride anticariogenic agent, either stan-nous or sodium fluoride, and is more effective than prior materials though mixed with much smaller quantities.          It can be supplied in a sectional kit wherein the ini-tially-separated wet and dry ingredients can be joined at the time of use.  It can be used as a self-administered prophylactic paste for mass treatment applications.

Abstract: METHOD OF MAKING BLOW MOLDED PLASTIC ARTICLES               ABSTRACT          A method of making blown plastic articles of non-circular cross-section, having convex exterior portions, such as a bottle of rectangular or oval shape, or having localized pro-tuberances.  The article is blown from a pre-form of inverted shape, i.e., the convex article portions are formed from concave pre-form portions.  Also, the concave, pre-form portions are of increased thickness to compensate for their greater subsequent expansion during blowing.          During final blowing, the non-convex portions of the article are first formed against the mold cavity - thereby stabilizing the partly blown pre-form in the blow mold cavity -and the concave pre-form portions are then blown to their final convex shape to complete the article.

Abstract: ABSTRACT OF THE DISCLOSURE           The prevent invention relates to a method of and a device for effecting electroslag remelting processes.  While effecting an electroslag remelting process by the proposed method an electrode is dipped into a slag bath.  Electric current is passed through the electrode and slag bath, heating the slag to a melting point of said electrode.  Upon establishing the molten slag bath and a metal pool said electrode is shielded by lowering on the surface of the molten slag bath a disc with an opening for the passage of said electrode so that the disc will float in the slag without coming in contact with the metal pool.  A device for effecting electroslag remelting processes, comprising a base-plate mounting a means for effecting an electroslag remelting pro-cess accommodating a slag bath and an electrode that is dipped thereinto and is encompassed with a protective-shield made as a disc in material whole specific density is lower than that of the slag of said slag bath.  Said disc is arranged directly on the surface of the slag bath, overlapping essentially all its sur-face area.

Abstract: ABSTRACT OF THE DISCLOSURE       A casing is placed in the fireplace and has an ad-justable damper on the rear wall communicating with a source of outside air extending through the rear wall of the fire-place.  A shelf extends forwardly from the rear wall of the casing above the damper and terminates spaced from the front wall.  An apertured grate engages the open underside and closes same so that air enters the damper into the casing and then flows around the front of the shelf and upwardly through the apertures within the grate to the fire.  A pair of detachable and adjustable fuel holding or fuel retaining components hook into the grate at any desired position.  The use of the device reduces the amount of air drawn from the room, provides better burning conditions and increases the heat radiated from the fire to the room.

Abstract: CONNECTOR WITH PERFORABLE INSULATIVE LINDER AND METHODS OF FABRICATING SAME            Abstract of the Disclosure An open-ended, B-wire type of deformable connector has a thin, perforable insulative liner secured to the inner surface of the inner one of a pair of telescopically coaxially disposed metallic sleeves in accordance with several preferred liner assembly methods.  The liner is positioned so as to overlie the distal ends of an array of insulation-piercing protuberances formed in the inner sleeve, and to extend con-tinuously in both the circumferential and longitudinal direc-tions at least to the perimeter of the array.  During assembly, while the inner sleeve is being fabricated out of strip stock in a progressive manner, each liner in the form of a section of thin, plastic film stock is positioned on and firmly secured (such as by pressure bonding) to the partially fabrica-ted planar sleeve section along at least the solid wall border regions thereof (surrounding the array of protuberances).  As such, the assembled liner not only remains taut in the axial direction while overlying the distal ends of the protuberances of the fabricated sleeve, but presents no peripheral edge obstruction to inserted conductors, particularly at the open end of the composite connector as assembled.  The preferred methods of assembling the liners are also advantageously conducive to high volume, automated manufacture, at minimal cost, as such assembly may be carried out sequentially with the work functions normally performed on the strip stock from which the inner sleeves are fabricated.

Abstract: CHANNEL SELECTING APPARATUS WITH       REVERSIBLE COUNTER              ABSTRACT OF THE DISCLOSURE      A tuning system for a digitally controlled electronic-ally tuned tuner with automatic  fine tuning (AFT) constantly operable to hold the tuner at a predetermined optimum fre-quency setting, especially a television channel.  A reversible counter provides the digital signal to control the tuning or the tuner and is, itself, deliberately shifted from one setting to another by pulses from a source, such pulses being applied to the UP input terminal or the counter as up-tuning pulses to shift the tuner frequency higher.  Pulses from the same source a-e also used as down-tuning pulses when applied to the DOWN input terminal of the counter. A frequency divider divides the frequency of the tuning pulses to a lower frequency sup-plied to two AFT AND circuits.  One output logic up-tuning instruction signal EU of the AFT circuit enables the up-tuning AFT AND circuit only in a certain sub-range below the desired frequency.  The other output logic down-tuning instruction signal ED of the AFT circuit enables the other AFT AND cir-cuit only in a certain cub-range above the desired frequency.          Consequently, deliberate application of up-or-down-tuning pulses to the UP or DOWN terminals changes the count as desired, being only partially counteracted by the lower frequency, AFT-controlled pulses to the opposite counter terminal.

Abstract: ABSTRACT OF THE DISCLOSURE           Fixed pattern odd/even noise in the video signal output from a self-scanned photosensor array is substantially eliminated by integrating the video signal at the cell scan rate, and converting the resultant to a pulse having a width proportional to the charge current generated by a photosensor cell.  Even and odd pulses corresponding to alternate sensor cell video signals are produced, and the pulse widths are compared to form a correction signal.  A current sink responsive to the correction signal adjusts the output of the integrator during even cell scans to eliminate fixed pattern odd/even noise in the output video signal.           In a specific embodiment, the fixed pattern odd/even noise correction system coacts with an AGC control system and a black reference control system to substantially eliminate fixed pattern odd/even noise and cell clock noise in the output video signal, and to provide an effective system immunity to variations in the coupling capacitance of the photosensor array.
